Need to fix Camera App

on a rainy afternoon, drinking milk with extra strong coffee nestle , I moved all the files present in "% USER% \ Pictures" folder to "OneDrive" folder. The "Camera App" began to save selfies made with my integrated webcam in the "OneDrive\Camera Roll" folder. I want the "Camera App" save the images in the default folder again, but I'm not having success, every time I delete the "Camera Roll" folder (which is inside the OneDrive folder) the "Camera App" opens and then closes almost instantaneously.
